The Hartke 4.5XL Bass Cabinet promises a particularly powerful and transparent bass sound. For example, four 10-inch Hartke XL drivers with the typical aluminum cone and a 5-inch aluminum tweeter ensure a clean and even reproduction of all frequencies between 30 Hz and 12 kHz, so that even five- and six-string electric bass is skillfully reproduced. With its 400 watts of power and 8 ohm impedance, the Hartke 4.5XL is equally well suited for building a large stack or for stand-alone operation with a powerful bass amplifier.
